in order to simplify the setup process to use streamline profiler do you provide kernel images (with properly configured kernel and a filesystem that contains the kernel source/headers) for at least one of the off the shelf tablets (or phone)  ? (models from asus, motorola, samsung etc...)

thank you.

    Tablet kernel and file systems will need to come from the tablet vendor.

    Streamline ships the kernel "gator.ko" and daemon "gatord" components as source code, so you can recompile for whatever platform you are targeting.


    thanks for your reply,

    tablet vendors have no interest in releasing their source code to developers, they sell hardware not software support, if it is a prerequisite for streamline it would be a good idea for arm to work on it for their DS5 users (vtune on windows for example asks nothing to their users).


    we did recompile gator.ko and gatord but after a streamline capture, the results of the analysis says the most of our app's cpu time is spent in [kernel] without any further details even tough i have CONFIG_DEBUG_INFO=y in /proc/config.gz. did i miss an option in streamline capture to have analysys information for the kernel ?

    regards.
